The Atlas · Woodland Hills, Los Angeles County, CA

Water filtration in Woodland Hills.

Woodland Hills runs on LADWP water, which is disinfected with chloramine rather than free chlorine. That matters because the carbon block stage in a typical whole home filter has to be sized differently to strip chloramine than it does for free chlorine. We size every system to the actual supply before we install.

The Water — Where it comes from

The local supply, in plain language.

Woodland Hills is served by Los Angeles Department of Water and Power. A blend of State Water Project deliveries from Northern California, Los Angeles Aqueduct flows from the Eastern Sierra, Colorado River water from Metropolitan Water District, and local groundwater. Disinfected with chloramine rather than free chlorine.

Common local concerns

  • · Chloramine disinfection byproducts (TTHM HLRAA 34.4 ppb per LADWP 2024 CCR, MCL 80)
  • · HAA5 14.9 ppb (MCL 60)
  • · Hardness at 6 GPG for the MWD Jensen supply (112 ppm CaCO3 avg); local San Fernando Basin groundwater blends can push higher
  • · Arsenic 3.5 ppb average, sampled up to 8.4 ppb in some zones (MCL 10 ppb)
  • · Hexavalent chromium (Chromium-6) at trace levels (<0.4 ppb) in the LADWP 2024 CCR
